You bet. You're implicitly stating that you believe there is no Bleem?! Yeah, belief is right there in the statement! Thanks for proving my point!
If you have factual evidence that Bleem doesn't exist, I'd grant you that it's a statement of fact. But, without that, it's merely a belief. Right now, there is no proof that god doesn't exist. It's hard to prove a negative anyway. Therefore, stating that god doesn't exist is a belief rather than a statement of fact. Logic.
I consider myself to be agnostic. I think it is unlikely that god exists, but I don't know for a fact that s/he doesn't exist.
